Reliable Manual Reset Circuit Breakers for 12V DC Applications – Type 3 Breakers

Manual reset circuit breakers, also known as type 3 breakers, provide dependable overcurrent protection in DC applications rated up to 12 volts. Designed for safety, these breakers operate continuously until tripped, then remain off until manually reset by pressing the indicator button, ensuring control and stability in circuit management. These breakers are ideal for marine and recreational vehicle applications where secure and consistent power protection is essential.

Engineered to meet RVIA and S.A.E. J553 specifications, these manual reset breakers are durable and suited to extreme environments, with an operating temperature range of -40°F to 185°F (-40°C to 85°C) and a storage tolerance from -40°F to 260°F (-40°C to 125°C). Available in rugged plastic housings, the breakers come with mounting hardware, and users can choose from three styles: with a standard mounting bracket, with a parallel mounting bracket, or without a bracket.
